I recently got my saxophone and i am really enjoying learning on it and playing the instrument. I can play a few songs now, and im getting better each time i pick it up. however, i find that im getting a few bad notes now and then. it is usually the 'G' note (when using the octave key), and the low 'D' and 'C'. The G is sometimes muffled and sounds bad, and sometimes the low D and C go up an octave when im not pressing the octave key. i can get the notes sounding good by moving my lips, putting more of the mouthpice in my mouth and sometimes playing a bit louder. i was just wondering if anyone else experienced these problems and if anyone has any embrochure techniques/tips that apply to these problems or any tips in general. thanks
